Abstract: The invention comprises a portable, multi-stage filtration system utilized in filtering water for an oil and gas stimulation process commonly known as fracking. Three stages are used, the first being a straining operation reducing the size of particulate matter in the water to about three-eighths of an inch. The second stage is a centrifugal separator, reducing the particle size to about 50 microns. The final stage utilizes a cartridge-type filter giving a final particle size in the water of about 5 microns. In this manner, water which is injected into the well head during the fracking process and which is obtained from readily available sources such as ponds, streams and the like is relatively free of particulate matter which can foul the fracking process. The invention, by virtue of being mounted on a trailer, is portable and thus can be easily moved from site to site.

Abstract: A detergent dispenser for a brush having a rotatable impeller driven by a jet of water. The dispenser has a tank connected to a valve having a blade positioned to intercept the flow of water around the impeller, part of the water passing into the tank to be mixed with the detergent to be dispensed into the flow of water around the impeller prior to the jet of water driving the impeller.

Abstract: The improved racquetball racquet has a strung surface which is larger in area than the strung surface of a conventional racquet, and in which the strung area is both longer in length and width than the strung area of a conventional racquet. However, the overall weight and balance of a conventional racquetball racquet which have proven necessary for good playing characteristics for all such racquets have been maintained. The racquet has synergistically combined the weight of the racquet, the center of mass of the racquet, the stiffness of the frame, and the response characteristics to create a racquet of sufficient durability with a larger "sweet spot" to facilitate the playing of the sport and to increase the level of skill, particularly of the novice and intermediate players.

Abstract: A tin brightener composition and plating bath utilizes a disubstituted naphthalene having at least one substituted aldehyde group thereon.

Abstract: A system for optimizing the printing of photographs. For color prints, a piece of photography paper is progressively and sequentially exposed to varying amounts of light of the primary colors, developing a color matrix on the paper. A neutral grey area on the paper identifies the optimum settings for the color filters and the exposure settings for the print system. A similar technique is presented for development of black and white prints by the generation of a grey level matrix, varying as to exposure setting.

Abstract: The present invention relates to a new method for supporting a metal and/or a metal oxide on a crystalline aluminosilicate zeolite. The resulting products are useful as catalysts and are designated ZKU-5, ZKU-6 and ZKU-7 (Zeolite Kyoto University catalyst). These catalysts display superior catalytic activity and selectivity and have a longer life than catalysts of the prior art.One method of the invention involves crystallizing a zeolite composition in the presence of both a conditioning agent and a crystal seed supporting the metal and/or metal oxide, the latter providing a nucleus for crystallization. The conditioning agent comprises the lower analogs of a tetraalkyl ammonium cation. The resulting crystal can support one or more metals or metal oxides or a mixture thereof.The disclosure compares the catalysts of the invention with a known, prior art catalyst, namely ZSM-34.

Abstract: The invention encompasses the synthesis of telechelic, i.e., terminally functional, macromolecular monomers (macromers) and their subsequent homo- and copolymerization. The macromers produced are asymmetric, having dissimilar head and tail groups which provide independent reaction sites.
